Application tiled October To all wlw/m 'it may concern:

Be it known that I, lCnEN Mooor Bor):- ToN, of West Newbury, in the county ot llssex and State of lllassachusetts, have invented'certain new and useful Improvements in Railway Structures, of which the following is a specification.

This invention relates to an improvement embodied in elevated or surface'rozuls and having greater strength, durability and eiliciency than-islat present secured.

0f the accompanying drawings forming a sents, in front e evation, a standard singlerail structure suitable for cities, and the post below the girders 'is shortened for surface Fig.`2 is aV section on line 2--2 of Fig. 1. Fig. 3 is a section on line 33 of elevated.' Fig. 5 is a partly uncovered side view of the rail cap and the protecting side for holding it in'place. Fig. G is an end section exposing the'cap and entire girder,

a firm support to a cross tic where project' ing and elevating for spans of fifty feet or more may be required.

The same reference characters indicate' the same parts wherever they occur.

Y) and 711 represent hex girders held by any suitable means for operatinfr as guides ofva single-rail train, as conduits for electric power; and they are properly insulated to support wooden cross ties (see Fig. 7) where necessary beneath c represents cables for conveyin',r ,r power, or electric wires for telegraph and'telephone.

'Referring to Fig. 6, d indicates the ca of a girder rail e, fr indicates the triang e, g indicates the steel network, and the dotted lines n and n* indicate the continuous covering of the rail between the ties, excluding all moisture from said girder rail, and the bolt a unites the steel that holds the cement both of the wide tie and of the continuous ce ment together.' j represents the body of cement within and around said steel4 which holds it lirmly together.

In Fig. 7, fr is the support-ing rod for the cross tie. l, which is in turn supported by the posts m and m. v

The rail-shown in Fig. 6 is a combination ot' cement. and steel. The waist is rolled with the base to a depth much if three-fold in depth, has nine-fold the strength oi' the metal in the Waist and base as now employed. It is also supported by the cement with one-hall:` the strength of granite, and is so held and covered, if moisture be excluded, as to have greatly increased durability and strength. The cap of the rail is shown as slanting downward to any need ed angle, and thus automatically grip ing` the 'cement to the steel waist instead o detaching it from it, and also roofing it from moisture by its form in the lmetal and in the cement; and the ca of the raihpainted with asphalt. will exclu e the Water and corrosion for, an indefinite period lif the asphalt tar be applied at intervals of one or more years.
